  hw/mips: Have mips_cpu_create_with_clock() take an endianness argument (2024-10-15 12:21:06 -0300)

One checkpatch warning due to wide comment:

  WARNING: line over 80 characters
  #108: FILE: hw/i386/multiboot.c:380:
  +    stl_le_p(bootinfo + MBI_BOOT_DEVICE, 0x8000ffff); /* XXX: use the -boot switch? */

----------------------------------------------------------------
Remove some target-specific endianness knowledge from target/.

For MIPS, propagate endianness at the board level, using QOM property.
----------------------------------------------------------------
